Lists of publications on vegetable topics, T. Greiner (N. Y. State Tcp. 

 Grotoers' Assoc. Rpt., 1911-1913, pp. 215-225). — This list, which is compiled on 

 behalf of the New York State Vegetable Growers' Association, comprises books, 

 publications, bulletins, etc., dealing with the general principles of vegetable 

 growing, insects, diseases, spraying, botany, breeding, canning, etc., together 

 with literature dealing with the culture of special crops. 



Difference in varieties of fruit and truck crops with reference to disease, 

 J. B. S. Norton (Rpt. Md. State Hort. Soc., 15 {1912), pp. 62-67).— Data are 

 given on observations of a number of varieties of apples with reference to their 

 injury from cedar rust, scab, blight, and russet from Bordeaux spraying, to- 

 gether with data on the susceptibility of different varieties of tomatoes planted 

 on soil infected with Fusarium wilt disease. 



An examination of the data secured for the resistance of apple varieties indi- 

 cates that freedom from one disease apparently has nothing to do with freedom 

 from other diseases, though a considerable number of varieties were affected 

 with both rust and blight. As indicated by the data there appears to be con- 

 siderable variation in the susceptibility of different varieties of tomatoes to 

 the Fusarium wilt. Certain varieties were practically immune and others 

 resisted attack until late in the season. 



Disease susceptibility of apple varieties in Ohio, A. D. Selby {Ohio Sta. 

 Girc. 133, pp. 53-56). — The author has here compiled in tabular form a com- 

 parative summary of the relative susceptibility of different varieties of apple.^ 

 to the diseases crown gall, collar rot, blister canker, twig blight, scab, bitter 

 rot, blotch, black rot of fruit and canker of branch, physiological fruit spot, and 

 fungus fruit spot. Notes are also given showing the special weaknesses of 

 different varieties. 



Spraying: New methods, materials, and ideas, O. S. Watkins {Trans. III. 

 Hort. Soc., n. ser., ^6 {1912), pp. 76-85). — This is a discussion of the author's 

 experience with fall and spring sprayings and five regular summer sprayings of 

 apples, designed to protect against insects and fungi. 



It is statetl that high pressure spraying causes much injury to the fruit and 

 leaves by forcing the granular particles of lime through the epidermis, making 

 an opening for copper which is said to be injurious. It is thought that 125 

 lbs. is as high a pressure as is safe to use. The removal of every apple at 

 harvesting is considered necessary to prevent diseases being carried over to the 

 next crop. 



Promising new fruits, W. A. Taylor and H. P. Gould (U. S. Dept. Agr. 

 Yearbook 1912, pp. 261-278, pis. 8). — In continuation of similar articles (E. S. 

 R., 27, p. 537) historical notes with descriptions and color plates are given 

 of the following new or little-known fruits and nuts that are considered worthy 

 of more extensive trial : Eastman, Monocacy, and Summer King apples; Douglas 

 pear ; Chesapeake strawberry ; Ormond persimmon ; Pollock avocado ; and 

 Major, Burkett, Warrick, Havens, and Owens pecans. 



The precooling of fruit, M. Cooper {Cold, 4 {1913), No. 10, pp. 183-189, 

 figs. 2). — A descriptive account of the car and warehouse precooling methods as 

 recently developed in the United States. 



[On the lateral shoot-forming tendency of various kinds of fruit trees], 

 O. Schindlee (Ber. K. Lehranst. Obst u. Gartenbau Proskau, 1911, pp. 27-29, 

 figs. 2; in Landw. Jahrb., 43 {1912), Ergdnzungsb. 1). — Lists are given of 

 varieties of apples and stone fruits which were found to have a special tendency 

 toward lateral shoot development, together with those which developed only a 

 relatively small number of lateral shoots and those in which lateral shoot de- 

 velopment was almost absent.
